There is only HEVC IDCT for 8- and 10-bit, and SAO for 8-bit. I don't doubt 
that those optimisations are good and mature. But in terms of coverage, 
compared to x86 and AArch64. That is embryonic IMO.

There are also no WASM guidelines in the optimisation doxygen file. How to 
write good assembler that runs fast on x86 and on AArch64 with intrinsics is 
not explained or referenced either.

To be clear, I'm not *faulting* anyone, and the RISC-V stuff, that I've been 
involved with, is also in many ways "embryonic" if less so than WASM's.
